Call your doctor if there's no improvement after taking antibiotics for 48 hours. Children taking an antibiotic who feel well and don't have a fever often can return to school or child care when they're no longer contagious â usually 24 hours after beginning treatment. But be sure to finish all the medicine.
An advantage of this option is that if the infection is indeed strep, 24 hours on an antibiotic renders the patient noncontagious, allowing a return to school or work after just a dayâs absence. With or without treatment, Dr. Bisno said, strep infections are limited, and most people are better within three or four days. Furthermore, he said, it is safe to wait several days â and perhaps as many as nine days â before starting antibiotic therapy without compromising the chances of preventing rheumatic fever.
